J-SEAL TPER Joint Seal

Product Description

CORKJOINT J-Seal® TPER Joint Seal, made from Thermoplastic Elastomeric Rubber, is a pre-formed joint seal for use in expansion and construction joints in concrete to prevent the egress of water through the joint, and to seal against the infiltration of debris and foreign matter from entering the joint. is a pre-formed joint seal for use in expansion and construction joints in concrete to prevent the egress of water through the joint, and to seal against the infiltration of debris and foreign matter from entering the joint.

J-Seal® TPER Joint Seal is extruded form a specially compounded cross-linked TPER material that provides resistance to UV, certain chemicals, oils, fuels, salt and sewage water. J-Seal® TPER Joint Seal can be fully submerged under water.

J-Seal® TPER Joint Seal provides high performance features for long-term durability and intergrity of the joint, for continuous use in low and high temperatures, and has excellent UV and weather resistance.

Advantages

  • Simple & easy to install
  • Can handle a wide range of movement
  • Creates an aesthetically pleasing joint finish
  • Competitively priced against traditional joint sealing compounds
  • Provides a permanent & flexible seal at the surface of the concrete and inside the concrete joint
  • Acts similar to a waterstop and can be fully submerged in water
  • Does not work free from the joint, even when the joint is subject to expansion and contraction
    movements
  • Strong, robost and has excellent abrasion resistance
  • Available in standard concrete grey colour. Other colours available to match the colour of the substrate surface
  • Compatible with all different types of expansion joint fillerboards
  • Installs at a wide range of temperatures and climatic conditions with resistance to UV and many
    chemicals.
  • Factory made intersections are available for joint areas that intersect or transect each other
  • Ability to be used in areas where curves or radius joint positioning is required
  • Can be used in conjunction with other waterstop systems as added benefit/protection to the structure and to the system Joining by heat welding

Typical Installations

  • Formwork is to be placed into position where the joint is to be placed. The top of the formwork should be 6mm below the surface of where the top of the concrete is to finish.
  • J-Seal® TPER Joint Seal is placed over the top of the formwork and is secured in position by small tack nails or staples placed along the lower section of the seal (below the fin) into the formwork. Both sides are to be tacked and secured.
  • The first pour of concrete is ready for placement. Care should be taken that the concrete is fully vibrated around the fins of the J-Seal® TPER Joint Seal to achieve full integration of the fin into the concrete. Once the first pour has cured, carefully remove formwork from out of the J-Seal® TPER Joint Seal.
  • Cut expansion joint fillerboard to the full-face height of the joint and firmly insert and fit it inside the J-Seal® TPER Joint Seal. A high-quality expansion joint fillerboard should be used and recommended is CORKJOINT’s Jointflex or CORKJOINT’s N.E.C Cork Fillerboard. Width of the fillerboard to be the same width as the J-Seal® TPER Joint Seal or similar.
    Insert expansion joint fillerboard fully into the J-Seal® TPER Joint Seal and adhere the fillerboard onto the face of the first concrete pour. Placement of the second pour can now take place. Again, care should be taken that the concrete is fully vibrated around the fin of the J-Seal® TPER Joint Seal to achieve full integration of the fin into the concrete.
  • If J-Seal® TPER Joint Seal is to be used for a construction joint, then an expansion joint fillerboard is not needed to be positioned on the face of the joint. A small piece of expansion joint fillerboard will need to be placed inside the J-Seal® TPER Joint Seal to the width and depth of it. The second pour of concrete can then be poured against the face of the first pour.
  • If joints intersect or transect, use factory made intersection pieces. Straight butt joins must be heat welded together using CORKJOINT’s specialized heat welding equipment. Installation training and welding equipment are available upon request.

Note : For full installation method guidelines, please also refer to our J-Seal® TPER Joint Seal Installation Method Guideline data sheet.

Design Parameters

  • J-Seal® TPER Joint Seal must be installed to CORKJOINT’s recommended Typical Installations as stated on Page 3 of the Product Brochure.
  • J-Seal® TPER Joint Seal can be used in conjunction with other waterstop systems as added benefit/protection to the structure and to the other system. Consult CORKJOINT for product suggestions and suitability.
  • J-Seal® TPER Joint Seal must be heat welded together at butt and intersection joints. Upon request,
  • CORKJOINT is able to train and provide the specialized welding equipment to perform this procedure.

Note : The product’s design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.

Site Jointing

 CORKJOINT recommends the use of its specialized welding equipment for on-site welding which consists of thermostatically-controlled welding blades and special welding jigs (each type of CORKJOINT J-Seal® TPER Joint Seal requires its own welding jig to suit the particular shape). On-site joining is a simple exercise using CORKJOINT Heat Welding Equipment comprising of an adjustable welding jig and heating blade. The ends of the waterstop are cut square and placed into the adjustable jig. The ends of the waterstop then slide up against the heating blade and bring the two ends together until the molten ends of the TPER fuse. When ordering welding equipment, please advise profile number of waterstop required.
